So, I downloaded a map called Straßenbahn Forsthausen.
The point is that the game runs very bad (15-20fps), and it's not like it's a very high quality map ATM (I mean the number and detail of objects etc).
I don't have a NASA computer, but it's not that bad:
CPU: Intel i5-4460 (3,2GHz)
GPU: nVidia GTX960 (4GB VRAM)
On the diorama map (I know, it's not that detailed) I get around 50-60 fps, on this map I get 15-20fps, and even the animations and the physics are slugging at this point.
I have a guess it's because of the vegetation objetcs (since it runs smoother on parts with less trees).
I don't think this detailed, 3D tree model is a good idea in LOTUS, or at least not with this engine (32bit, with this graphic engine).
It doesn't look that good at all (it's just too homogeneous, unrealistic). From far distances, even the OMSI-like, 2D trees look better than this, but I'm sure these trees have over a 1000 polygons or even more. And in areas like this (smaller or larger forrest-like map parts) it kills the performance.
Is there a hope this vegetation performance will change, or should we just try to model low poly trees for maps, and use these high poly trees only near the tracks?
(Also, will there be an option to not save screenshots in .png? It'd be nice if they would be saved in rather jpeg than png, which makes all of the screenshots >3Mbit)
